applicant meer D'aemitr 13, 1.897. lsain No. 661,693. dit man.:

Be it known that I, THOMAS L. MCKEEN, a citizen of the United States, residing at New York, in the county-of New York and State of New York, have invented'certain 4new and useful 4Improvements in Railway-Car Constru'etiong and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the' art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in thel construction of -railroad-cars. A

It hasfor its object to secure great strength and at the same' time the proper elasticity in the completed car; and 'with these ends in view'my invention onsistsin the particular construction n'dfrrangement of parts here- 2o inafter more fully ldescribed and claimed. Inorder that those skilled in the art may fully understand myimprovedcar, I will procross-section online x m of Fig. l.

.coed to describe the construction of the same,

referring' by letters and'numerals to the ac! companying drawings, in which- Figure 1 is a top or plan view'of one end of vthe frame orsupport for the car body and 'platform.` Fig. 2 is an end View. Fig. 3 is an enlarged longitudinal section on the ,line y y. of'Fig. 1, the horizontal dotted lines representing metal plates, which are shown in cross-section at Fig. 5. Fig. f1 is a vertical Fig. 5 is ,a 4similar View on line .e .e of Fig. 1. Fig. 6 is 'aside elevation and a section through the used in the construction. Fig. 7 is a top or plan View of attachment of draft-rigging. Fig. 8 is a side view, partly in section, of the same. Fig. 9 is a cross-section showing the attach ent of the draft-rigging, and Fig. 1'0 is a de ail sectional view showing the draft- `rigging attachment to I-beams in lieu of the ordinary longitudinal Wooden sills.

Similar letters of reference and 4numerals indicate like parts in the several iigures of the drawings. 1A A are the central longitudinal car-body si ls.

A A are longitudinal-side sills arranged' a suitabledistance outside of the. car-body 13 is the end sill of the car, and it is framed onto and connected in the usual manner withA p thecentral and side sills A A', which extend 55 vbeyond said end sill and constitute platformsills C C. l

D is the end sill of the platform, framed in the usual way to the side sills A A.

E E are the draft-timbers, to which the draft- 6o rigging is secured, and F designates the exterior platform-sills of the platform, which constitute supports for the steps. V

1 l are metal plates of any suitable thickness, preferablyy three-eighths of an inch, and 65 are formed with or without bottom flanges 2, (see Fig. 6,) which tend to stiien the plates'. These plates extend any' suitable distance longitudinally and are sufficiently deep to embrace or cover the sides of the car-body' sills A and thev underlying draft-'timbers At the point where the plates l pass under the end sills Bv they are cut and turned down to form horizontal wings 4, which lie under and support the said sills B, and the extreme 75 ends of said plates are out and turned down .to form horizontal wings 7, which lie under.

and` support the platform end timbers D. (See Fig. 6..) Horizontal screw bolts and nuts 3 are employed to secure the plates in posi- 8o tion against the sides of sills, and Vertical bolts and nuts 5 6 are employed to secure the wings 4 and 7 in their supporting positions under the end timbers Band D, or, if thought desirable, the rail-post S and a nut 9 may be 85 employed to secure the Wing 7 in position.- At the point where the ditch-plates" 10 are locatedthe plates 1 and 19 are slotted,as shown at 11, Fig. G, to permit the passage of the Hitch-plates, which are se'cured in the usual 9o manner by screw-bolts 1,2. (See Fig. 1.)

In order to still further strengthen the oonnection of the plates 1 at their intersection with the end sill B, a ,plate 13, otsuitable width and thickness,passes through lthe end 95 sill, and lying against the metal plate lis firmly secured in position by horizontal screwbolts ltpassing through vthe plate 1 and sill A and fastened by nuts 15.

' The truss-rod 16, of ordinary construction roo and arrangement, is secured at each end to eyebolts 17, which pass .through the plates 1 and subsills E, and are drawn together-and firmly held byturnbuckles 18, thus holding I platform-sills F and is formed with wings. similar to the wings 4 and 7 of the plate 1 and, like said wings, lie under, are secnredto, and support the end sill ll and the platform end timber D, bolts and nuts 3, 5, and o, similar to those aheady described, being em.

ployed to secure the plate and its wings in position. At Fig. 3 t-he dotted lines show the plate 1 secured to the car-body sills A and draft-timbers E, and the plate 19 to the step sills, thc former extending farther to the rear than the latter, the double row of dotted lines near the bottom of said figure representing the strengtliening-tlangcs along the bottom edges of the plates 1 and 19.

0 is a brace-plate under the platform to prevent lateral strain of the latter. This brace is secured in position by vertical screwrods and nut-s u, asshown in Fig. z?, and by reason of its employment l am enabled to dispense with the ordinary carry-iron block, such as used inthe Miller platform, and thus permitting the bringing forward of the drafttimbers or 'subsills la under the platform end timber D, the auxiliary securing-bolts I), passing tliruuglrthe ordinary carry-iron" of any suitable construction, the plate 2H, the subsills 0r draft-timbers E, and the central car-body sills A bind all together most sccurely.

2l is a truss-rod which l employ to assist. in the support of the car end sill ll, which is subjected umler the present heavy weight of the continuous platform to great vertical strain. 'lhis truss-rod in two parts passes through the plates 1 and lil, the draft-tin1 bers l, and step-timbers F, and is secured at the outer ends to the end sill l by screwboltsl 2; and nuts 25). 'lhe inner ends of the truss-sect ions are threaded and are connect ed by a turnlnichle 2l, by means of which they are drawn together in an obvious manner.

l isthe draft-rigging secured to the sil-ls A A, and instead of the ordinary method of securing the rigging by means ol' bolts passing vertically through the lloorof the car, the wooden sills, and drafttimbers I form the draft-rigging with side plates G" u", adapted to lie against the inside faces ,of the sills A and subsills ll, and l provide thc side plates with nipples ll, which enter recesses formed in the timbers and constitute dowels, which when the bolts l,which pass through the plates l, timbers A E, and draftrig,f. :ing plates G', are securely fastened by nuts J, a very rigid and strong connection of the draft-rigging is inade.

XVhile l prefer to use the construction shown at Fig. 9, as it is especially adapted to my otherwise-improved car construction, it

will be understood that my improved construction of draft-"igging, which involves the generic idea of connecting it by lateral rather than vertical bolts, may lie/employed with what is known as the I-beam sills 1 by con'- structing the side plates G to conform to the contour of the I-beams, as clearly shown at Fig. 10. The draft-rigging in every other partcular, except in respect to the manner in which it is secured in position, may be constructed in the ordinary or any preferred manuel'.

F2 is a body-bolster secured to the side timbers of the car-body by any suitable bolts and held against any longitudinal movement by shoulders near each end of the itchplate, as clearly shown at Fig. 4.

Having described the details of my improved car construction, what Iclaim asr new, and desire to secure by Letters Patent, is
